Abstract: An elevator system includes a hoistway, the hoistway having a plurality of landing floors each landing floor having a landing floor door. One or more guide rails are located in the hoistway to guide one or more elevator system components along the hoistway. An absorber is located at a hoistway pit and is supportive of a guide rail of the one or more guide rails. The absorber is configured to absorb loads imparted to the guide rail due to vertical translation and/or compression of the hoistway. A method of supporting a guide rail of an elevator system includes locating an absorber in an elevator hoistway in operable communication with a guide rail of an elevator system. Vertically-acting loads are transmitted from the guide rail to the absorber via the absorber piston thereby increasing a fluid pressure in the housing chamber.

Abstract: A hoistway access system for an elevator includes an access switch positioned at a selected landing floor 34 of an elevator and operably connected to a controller 46. A remote controlled lock 48 is located at landing doors of a landing floor providing access to a hoistway pit 36, and is operably connected to the controller. A safety actuation system is operably connected to an elevator car and operably connected to the controller. The controller is configured to command a drive system to drive the elevator car to an upper location when the access switch is activated, to define a selected safety volume in the hoistway defined by the hoistway pit and the elevator car, command engagement of the safety actuation system to stop and hold the elevator car, and command the lock to unlock when the safety actuation system is engaged, thereby allowing access to the hoistway via the landing doors.

Abstract: A safety system (105) for an elevator system (100). The safety system (105) includes a plurality of sensors (120) and a controller (110). Each of the plurality of sensors (120) is configured to produce an override signal when a landing door (112a) to which the sensor is connected is opened by manual override. The controller (110) is configured to instruct the elevator system (100) to automatically enter a special operating mode when the override signal is received from one of the plurality of sensors (120).

Abstract: An elevator car comprises a panel that is moveable between a closed position, in which the panel at least partially defines a sidewall of the elevator car, and an open position, in which an opening is provided in the sidewall to an area outside of the elevator car. A member is provided external to the sidewall and extends across at least a portion of the sidewall such that, when the panel is in the open position, the opening is spanned by the member. A mechanism is on one of the panel and the member. The mechanism is moveable between a first position, in which the mechanism is not engaged with the other one of the panel and the member, and a second position, in which the mechanism is engaged with the other one of the panel and the member such that the panel is held in the closed position.

Abstract: A monitoring system for an elevator system to ensure a predetermined elevator shaft clearance is provided and includes an elevator car moveably disposed in an elevator shaft and guided along at least one guide rail, the elevator shaft having a top surface and a bottom surface. Also included is a counterweight moveably disposed in the elevator shaft. Further included is a position monitoring device monitoring a position of at least one of the elevator car and the counterweight relative to at least one of the top surface and the bottom surface. Yet further included is a braking device actuated to initiate a braking event in response to detection of the position of at least one of the elevator car and the counterweight being within a predetermined distance from one of the top surface and the bottom surface.

Abstract: A hoistway door locking system includes an elevator shaft. Also included is an elevator car disposed within the elevator shaft and moveable therein between a plurality of access openings located at a plurality of levels of the elevator shaft. Further included is a plurality of locking mechanisms, at least one of the plurality of locking mechanisms being located at each of the plurality of access openings, wherein each of the plurality of locking mechanisms is operable between a locked condition and an unlocked condition, and wherein only a single locking mechanism may be in the unlocked condition at a specific time, the unlocked condition occurring upon alignment of the elevator car and the respective access opening having the single locking mechanism.
